NON-REFTLLABLE BOTTLE.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed May 1'7, 1913. Serial No. 768,318.

To all whom it may concern Beit known that I, DAVID BIRCH, a subject ofthe King of Great Britain, residing V at New York city, in the county ofNew York and State of New York, have invented new and usefulImprovements in Non-Refillable Bottles, of which the following is aspecification.

This invention relates to non-refillable bottles and has for its objectto provide a means,

oughly relic ble means which may be applied to bottles in general use,and which means when in place are so arranged as to render the bottlepractically fool-proof.

To these ends the invention consists in the novel details ofconstruction and combination of parts more fully hereinafter describedand particularly pointed out in the claim. I

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in-alltheviews: Figure l is a side elevational view of the upper portion of abottle neck and showing my invention applied thereto. 'Fig. 2is alongitudinal sectional view thereof. Fig. 3 is a plan view of one of thebaffles. Fig. 4

vis a cross sectional view thereof. Fig- 5 is a plan view of another oneof'the baffles. Fig. 6 is a cross sectional view thereof. Fig. 7 is aplan view of the spring, and Fig. 8 is a cross sectional view thereof.

Referring to the drawings in detail 1 designates the upper portion ofthe bottle neck, provided with a series of exterior annular grooves orchannels 2. V

3 designates an enlarged sleeve provided with the interior grooves orchannels 4:, and 5 designates a cement filling which enters the groovesand which, when it becomes hardened, rigidly secures the sleeve to theneck of the bottle. r

The sleeve has its interior walltapered as at 6 to provide a seat for aweighted valve 7 and is shouldered as at 8 to provide a chamber 9 andagain shouldered at its upper end as at 10, to provide a recess 11adapted to receive a keeper 13 which is provided with a stem 14: thatprojects within the central apertured portion 15 of the valve and acts.

outer end of the sleeve.

as a guide for normally insuring the proper seating of the valve whenthe bottle is in its upright position.

The upper wall of the sleeve is provided with a series of outletopenings 16 which communicate with the chamber 9 and these openings areadapted to be normally covered by means of a cap 17 which fits over theThe cap is also provided with perforations 18 to correspond with theopenings 16 and may be turned so as to bring its perforations intocoincidence with the openings 16 when it is desired to remove some ofthe contents of the bottle. To prevent the removal of the cap from thebottle it has a portion 19 on its side spun into a groove formed in theside of the sleeve as shown.

Located within the chamber 9 are spaced baffles 20 and 21 which aredesigned to render the bottle fool-proof and thereby prevent theinsertion of instruments into the bottle neck to manipulate the valve.These baflles are centrally perforated to permit the stem of the keeper13 to be inserted therethrough, and with relation to which they mayturn. The baffie 20 is provided with a series of peripheral notches 22and the bafiie 21 is pro vided with a series of perforations 23.

A light spring 24 of suitable construction, such as the spider-shapedone shown, is also located within the chamber 9 and engages with boththe under surface of the baffle 21 and the top of the valve for normallyseating the valve when the pressure of the liquid has been removedtherefrom.

' It will be'observed that when the parts of my improvement are in theirnormal position as shown in Fig. 2, the valve completely closes theentrance to the bottle, thereby rendering it practically impossible torefill the bottle, but when necessary to discharge the contents afterthe bottle has been origicap is then turned so that its perforationsWill be brought out of coincidence With the arrangements of partsWithout departing from the spirit of my invention and therefore I do notWish to be limited to such features except as may be required by theclaim.

What is claimed as new is:

In a non-refillable bottle a sleeve provided at its sides With outletopenings, a valve mounted Within the sleeve, a keeper held in the sleeveand provided With a stem upon Which/the valve is slidably mounted,baffles mounted upon the stem one baffle having an spaced from eachother said baflles having in V the vicinity of their peripheriesopenings Which lie at one side of the openings in the sleeve and aspring interposed between the valve and the innermost baffle and servingto hold the valve in a closed position in the sleeve and the baflies infrictional contact with each other;

In testimony whereof I afiix in presence of tWo Witnesses. V 7 I DAVIDBIRCH. Witnesses: r v
